1.0 INTRODUCTION

This report addresses if Savannah River Site (SRS) subcontracted construction trade workers (CTWs) 

were monitored differently from prime contractor (DuPont) CTWs when doing the same types of work 

during the 1980s. The Oak Ridge Associated Universities (ORAU) Team reviewed SRS documents 

to evaluate radiological monitoring of subcontractor CTWs compared to DuPont CTWs.

ORAUT-OTIB-0081, Internal Coworker Dosimetry for the Savannah River Site (ORAUT 2016), 

describes a method to allow the identification of CTWs using a site-applied identifier, specifically the 

SRS Payroll Identification (PRID) number. The PRID contained a prefix letter or number for the type 

of worker payroll referred to as Roll, an optional two-digit code for craft, and a 4- or 5-digit badge 

number. Roll prefixes changed over time. Rolls T, 0, and 1 designated DuPont salaried employees. 

Roll 2 designated local operations hourly workers. Roll 3 designated Wilmington CTWs (engineering 

and support workers). Roll 4 designated non-DuPont local hourly workers, most of whom were 

CTWs. Non-DuPont workers other than subcontractor CTWs were tracked in Roll 5. Over time, some 

non-DuPont CTWs were added to Roll 5. In 1985, Roll 6 was added for CTWs (DuPont 1954, ca. 

1961, 1981a, 1988; WSRC 1990a). The ORAU Team noted TR and TB prefixes were used for 

certain temporary workers and the PS prefix that was used for employees of Diversco (DuPont 1983–

1985). 

Monitoring of workers at SRS was accomplished through the use of procedures and building safety 

plans. For certain short-term tasks, typical of CTW activities, SRS used Job Plans and Special Work 

Permits (SWPs). In special circumstances, work clearance permits and confined space logs were 

also used. Thus, the following forms associated with these plans, permits, or logs were reviewed for 

this report:

• Job Plan,

• SWP, 

• Work Clearance Permit, and

• Confined Space or Vessel Entry Log. 

Attachment A provides examples of each. Each form described the planned activity, documented the 

monitoring and exposure control requirements, and had sections to list the names of the assigned 

workers under that plan or permit.

2.0 IDENTIFICATION OF WORKERS

In June 2016, the ORAU Team obtained several hundred Job Plans and safety permits for work at the 

high-level caves (HLCs) in Building 773-A between October 1979 and December 31, 1986. These 

Job Plans and safety permits are grouped by year. Table 2-1 provides the date ranges and 

associated references for the 21 documents that contain these forms. The coverage of Job Plans 

over the period under evaluation is shown in the timeline in Figure 2-1. Green indicates the range of 

dates covered by Job Plan files while the color red indicates Job Plan files not found for those dates. 

The Job Plan files listed in Table 2-1 are not necessarily all of the Job Plans used at the HLC during 

the period. Using the method described in ORAUT-OTIB-0081, Internal Coworker Dosimetry for the 

Savannah River Site (ORAUT 2016), the ORAU Team reviewed the job plan forms and extracted the 

names and PRID numbers of CTWs. Identified workers were sorted by employment (i.e., DuPont or 

subcontractor) and by year. The Team then reviewed each Job Plan and work permit chronologically 

to identify CTWs from Roll 2 (DuPont CTWs) and from Rolls 4, 5, and 6 (subcontractor CTWs).

Figure 2-1. Timeline showing availability of Job Plans (green = Job Plans found; red = brief portions 

(days) not found). 

Job Plans were used to permit all types of work and, therefore, covered all types of SRS workers. 

The “Done By” line of the Job Plan showed which organization was to do the work. Line 8, Procedure 

review with Crafts (Maint, E&I, T&T) was used to indicate work to be done by CTWs. Figure 2-2 

shows these on an example Job Plan (DuPont 1982b).

The ORAU Team identified Job Plans for maintenance or construction work on which: 

• Any designation indicating Maintenance, Maint, E&I, T&T, AM, Construction, or Const was 

written in the “Done by” box as shown in Figures 2-2 and 2-3 (DuPont 1982b, 1984a),

• Box 8 of the Job Evaluation section contained Yes regardless of the “Done by” box, or

• Neither of the above were true, but the form contained recognizable1 CTW names in the 

Estimated Exposure section. 

These forms were separated into a subset for further evaluation.

Workers who were listed on an SWP (Figure A-2) and its Supplementary Time Sheet page 

(Figure A-3) are usually subcontractor CTWs. These forms were also included in the subset for 

further evaluation. Names and PRIDs are recorded in the Name and Payroll Number columns as 

shown in Figure 2-4.

Work Clearance Permits and Confined Space and Vessel Entry Logs were also included in the subset 

of forms for further evaluation of workers. These form types represent generally about 5% of the total 

forms reviewed. Examples are available in DuPont (1982a, 1983c, and 1985c).

Figure 2-4. SWP Name column (DuPont 1982b). 

The ORAU Team reviewed names on each form in the subset by year. A worker was included in the 

annual list of names if the entry had at least an initial and last name with a PRID, otherwise the entry 

was not considered. Names and PRIDs were handwritten, sometimes scribbled, on the forms and 

often were difficult to decipher. The Team compared difficult-to-read names or PRIDs to legible 

entries on Job Plans with similar work and departments. For example, a name on a Job Plan for 

maintenance in C Wing was compared to names on other Job Plans for maintenance in C Wing. 

In some instances the name was not legible while the PRID was. In other instances the name was 

legible but not all of the PRID was legible. In both of these cases, SRS external dosimetry logs were 

used to assist in resolving the worker’s identity. Names and PRIDs of workers in Rolls, 2, 4, 5, and 6 

were recorded. Not all workers in Roll 2 were CTWs. Those not assigned to a CTW occupation were 

removed after evaluation using SRS job history cards.

Using the method described above, the ORAU Team identified 1,052 CTWs and was able to resolve 

1,047 name and PRID combinations (99.3%). Of these, 397 were DuPont employees and 650 were 

subcontractors. Table 2-2 lists the number of workers by year and type. Workers were listed only 

once per year even though each might have worked under more than one Job Plan during a year. 

Some workers were found in more than 1 year.

The Team assessed each of the Job Plans or SWPs linked to the workers’ names to determine if the 

job potentially required or led to bioassay. For example, the Health Physics Department (HP) could 

require bioassay in advance of a job by marking the “Give Bioassay Sample Before Leaving” box on 

the SWP as shown in Figure A-2, or by writing “bioassay required” in the required monitoring text 

boxes on the forms. HP also indicated on Job Plans when respiratory protection would be required:

1. No potential, or

2. Potential for intake.

A worker was counted as having a potential for intake for that year if any one plan or permit contained 

one of the indicators described above. However, it should be noted that a worker found to have no 

potential for exposure in a given year could have been exposed while working at other jobs in Building 

773-A or other SRS locations.

3.0 EVALUATION OF CTW EXTERNAL MONITORING

External dosimetry records were searched for each identified worker using their names and PRID 

numbers to determine when monitoring was performed for each. For each year, the percent of 

workers who were monitored was calculated for the groups DuPont CTW, subcontractor CTW, and 

total CTW.

Using the name, PRID data, and year, the Team searched SRS quarterly external monitoring reports 

for each worker to determine if the worker was monitored for external radiation at least once during 

the year (DuPont 1980d, 1980e, 1980f, 1981e, 1981f, 1981g, 1981h, 1982d, 1982e, 1982f, 1982g, 

1983d, 1983e, 1983f, 1983g, 1984d, 1984e, 1984f, 1984g, 1985d, 1985e, 1985f, 1985g, 1986c, 

1986e, 1986f, 1986g, 1987a). Figure 3-1 is a redacted sample of an external monitoring report 

showing subcontracted CTWs. 

Figure 3-1. Quarterly external monitoring report. 

Table 3-1 provides the number of externally monitored CTWs by year and employment type. All 

DuPont CTWs were monitored for 5 of the 7 years, while all subcontractor CTWs were monitored for 4 

of the 7 years. Results of external monitoring were reported by calendar quarters. While the quarterly 

results are not broken down into specific work or work areas during the quarter, results by quarter 

covered all job plans for the quarterly period as assessed in this report .

The significant monitoring disparity in 1985 was investigated and involved 20 subcontractor CTWs in 

1985 were found to have temporary badges. These electricians, pipefitters, and construction workers 

installed heating, ventilation. and air conditioning (HVAC) systems on the roofs of D and E Wings 

spanning 2 workdays in 1985 (DuPont 1985b, pp. 277–287). The Team found no records of external 

monitoring for these workers, although the Job Plan implies some of the workers were monitored by 

film badge and neutron dosimetry for a portion of the job. Two subcontractor CTWs with temporary 

badges were found to have installed tile in 1986 in a women’s change room, E-029 (DuPont 1986b, 

p. 301. While there were requirements for HP monitoring of roof-HVAC work (and no permit 

information available for ORAU Team review associated with the women’s change room tile 

installation), such data has not been acquired by the Team. HPs monitored each of these jobs

Results of air monitoring collected on the dates of these jobs in 1985 and 1986 were at background 

(DuPont 1985k, 1986p).

4.0 EVALUATION OF CTW INTERNAL MONITORING

The SRS routine bioassay monitoring program was based on work location with the chosen 

radionuclides and frequencies that HP determined from the exposure potential in each facility 

(ORAUT 2016). DuPont CTWs were part of that routine monitoring program in accordance with the 

bioassay control procedures (DuPont 1976). For other workers intermittently present in a controlled 

area (i.e., some subcontractor CTWs), bioassay monitoring was based on the Job Plan. In addition, 

HP could also request bioassay when airborne, surface, or worker contamination events and incidents 

were noted. With such events, incident-driven bioassay sampling was performed. Most 

subcontractor CTW bioassays were the result of job-based or incident-based sampling, although 

some subcontractor CTWs were routinely monitored for intakes of radiation.

The Team reviewed available SRS bioassay logbooks for each worker who was identified as having a 

potential for exposure to determine if the worker was monitored for internal radiation at least once in 

the year (DuPont 1980g, 1980h, 1980i, 1980j, 1980k, 1981i, 1981j, 1981k, 1981l, 1981m, 1981n, 

1981o, 1982h, 1983h, 1983i, 1983j, 1984h, 1984i, 1985h, 1986i, 1986j, 1987b, 1987c, 1989; WSRC 

ca. 1990b). Figure 4-1 shows a redacted example of a plutonium logbook with results for a 

subcontracted CTW in 1985. This review did not include fission product or tritium bioassays, both of 

which were collected from workers who performed certain jobs at the HLCs. 

Figure 4-1. Excerpt from plutonium bioassay logbook, 1985. 

The Team found no bioassay results for 550 subcontractor CTW-job pairings (255 unique 

subcontractor workers). To evaluate bioassay of subcontractor CTWs, the Team performed an 
Document No. ORAUT-RPRT-0083 Revision No. 00 Effective Date: 06/27/2017 Page 12 of 51

analysis of these subcontractor CTW-job pairings. The Team originally randomly selected 10 workers 

from the 255 subcontractors to evaluate with the intent of collecting their personal monitoring data 

during an SRS data capture. An additional 100 workers were later randomly selected from those 255 

subcontractor CTWs to retrieve bioassay results for further evaluation. Some workers were paired 

with jobs in multiple years, which resulted in 133 distinct subcontractor CTW-job pairings with no 

bioassay records. Table 4-1 gives the distribution of the selected 133 subcontractor CTW-job pairings 

with no bioassay records by year.

In November 2016, the Team performed a data capture at SRS to search for bioassay data for the 

110 CTWs for the given years. The data was separated by year and by job and by exposure 

potential. Crafts represented by the 110 randomly selected workers included boilermaker, carpenter, 

concrete worker, construction, driver, electrician, heavy equipment operator, ironworker, laborer, 

millwright, painter, pipefitter, radiographer, and sheet metal worker. Because of the few number of 

data points for 1980 and 1982, data for 1980-1981 and 1982-1983 were combined. The distribution of 

crafts is shown graphically in Figure 4-2 (DuPont 1981a, 1980a, 1980b, 1980c, 1981b, 1981c, 1985a, 

1981d, 1982a, 1985a, 1982b, 1982c, 1983a, 1983b, 1983c, 1984a, 1984b, 1984c, 1985b, 1985c, 

1986a, 1986b, 1986c).

monitoring.

During the data capture, the Team found bioassay data for 105 of the 110 workers (ORAUT 2017). 

For each of the 110 workers, the tasks described on the Job Plans were reviewed. For workers who 

appeared on more than one Job Plan in the same year, a task was selected that appeared to have 

provided the greatest risk of internal exposure for the worker. Tasks performed under Job Plans and 

permits reviewed for this report represent only a small portion of work done by most of the 

subcontractor CTWs. Certain subcontractor CTWs are likely to have been sampled in relation to work 

in other SRS areas during the same year as the year of the reviewed Job Plan or permit at Building 

773-A, or as part of routine bioassay. SRS ran a plantwide bioassay program. Results of bioassay 

obtained in other areas is still under evaluation for use in reconstructing doses from work in 

Building 773-A.

• These 773-A Job Plans were reviewed for:

• Craft;

• Date of the Job Plan;

• Task description and location;

• Type of monitoring (at the start, intermittent, or continuous);

• If respiratory protection was required;

• Results of alpha or fission product continuous air sampling for the location on the date of the

work; and

• Dates of collection of in vitro bioassay samples and dates of in vivo bioassay measurements.

Attachment B, Table B-1 provides the results of these reviews. Each row in the table represents a 

single worker in a single year. Note that no identifying information is shown and some workers 

appear in this table in multiple years, which results in a total of 133 rows.

Bioassay results available for a worker were examined based on the time between the date of the job

and the date of sampling with the time difference compared to bioassay frequencies given in DuPont 

1971. A worker was marked as being sampled for a particular radionuclide if the sampling time 

difference was less than or equal to the frequency given for the radionuclide.

• Workers with potential for intakes of plutonium in Building 773-A were sampled once every

three years by plutonium urinalysis or chest counting (DuPont 1971).

• Workers with potential for intakes of fission products in Building 773-A were sampled by fission

product urinalysis or whole-body counting annually (DuPont 1971).

• Workers with potential for intakes of americium in Building 773-A were sampled by americium

urinalysis every six months (DuPont 1971).

In addition to these checks based on bioassay frequencies, two additional checks were made: 

• Workers with results from tritium bioassay collected at 773-A or A Area up to 2 months from

date of work were noted as having tritium bioassay.

• Workers with results of bioassay from any other radionuclide, such as enriched uranium, within

1 year from the date of task were noted as having bioassay for that radionuclide.
Document No. ORAUT-RPRT-0083 Revision No. 00 Effective Date: 06/27/2017 Page 14 of 51

The Team also:

• Identified workers with results of plutonium bioassay collected within one year of the date of

job.

• Identified routine bioassay results for plutonium and fission products that indicated a

subcontractor CTW was on routine bioassay.

Of the 133 worker-job pairings, 88 required the use of respiratory protection. Table 4-1 shows the 

number of worker-job pair pairings by year.

While the Team found bioassay results for some workers that were not required by a Job Plan to use 

respiratory protection, the Team focused on the 88 subcontractor CTW-job pairings where workers 

were required to use respiratory protection. Table 4-2 lists summary data for these reviews by year. 

The total number with bioassay represent the number of workers with actual bioassay results 

(plutonium, americium, fission product or, rarely, tritium) within the above periods.

The percentage of subcontractor CTWs from the sample of 88 subcontractor CTW-job pairings 

monitored by bioassay ranged from 54.5% in 1984 to 78.3% in 1985. Thirty-four of the 88

subcontractor CTWs, or about 39%, using respiratory protection were on SRS routine monitoring at 

the time of the Job Plan. HPs monitored jobs requiring respiratory protection. By procedure they 

would require bioassay from subcontractor CTWs after such jobs depending on results of air 

monitoring or whether incidents occurred (DuPont 1976). Examples of the latter are given in Section 

6.0. Figure 4-3 depicts the numbers of workers monitored by bioassay as presented in Table 4-2. 

The total number of subcontractor CTW is shown in red while the total workers with bioassay is shown 

in blue. The total number of subcontractor CTW on routine bioassay is shown in green (DuPont 

1980h, 1980i, 1980k, 1980g, 1981k, 1981j, 1980j, 1981i, 1981l, 1981m, 1981n, 1983h, 1983i, 1983j, 

1984h, 1984i, 1985h, 1986h, 1986i, 1989; ORAUT 1987b, 1987c, 2017; WSRC ca. 1990c). 

Workers on short-duration jobs (less than a few days) were not likely to have been sampled unless an

incident in the associated work area led to an incident bioassay. The Team found bioassay results of 

coworkers on the same Job Plans for another 26% of the subcontractor CTWs using respiratory 

protection, although it is possible that the coworker bioassay was collected as a result of work on a 

different job or work location. The Team identified temporary workers with bioassay (DuPont 1984i, p. 

165; 1968, p. 38; 1985h, pp. 118, 120; ORAUT 1989a, pp. 136, 138, 150) including one who was 

sampled after an incident (DuPont 1987d, p. 122). 

5.0 EVALUATION OF WORKPLACE JOB MONITORING

All work locations in Building 773-A were surveyed and swiped for contamination on routine, defined 

frequencies. Airborne environments of work locations were continuously monitored for alpha and 

beta-gamma radioactivity (DuPont 1982i, 1982j, 1983k, 1983l, 1983m, 1983n, 1983o, 1983p, 1984j, 

1984k, 1984l, 1984m, 1984n, 1984o, 1984p, 1984q, 1985i, 1985j, 1985k, 1985l, 1985m, 1985o,

lists all known alpha and fission product airborne results for the Job Plans covering the 110 random 

subcontractor CTWs.

To fully evaluate the degree of monitoring of subcontractor CTWs, the Team reviewed sets of 

representative Radiation Survey Logsheets (RSLs) for Building 773-A. Logsheets of monitoring under 

Job Plans noted survey measurements, description of work and location, additional precautions or 

protections, and any observed contamination. For any observed personnel contamination, the results 

of decontamination efforts were also recorded. The RSL data were compared to Job Plan files 

covering the same dates, which resulted in the identification of several pairings of RSLs and the 

associated Job Plan. An example is presented for each year from 1981 through 1986. More 

complete sets of RSLs are known to be available at SRS.

(DuPont 1981p, 1981q). 

Under this Job Plan, subcontractor CTWs cut a HLD line in C-002 as part of a project to replace the 

drain leading from hot cells and laboratories on the first floor. The work was monitored on an 

intermittent basis. There was a note for HP to be notified when work moved to a new area or when 

cutting involved certain painted areas. Transferable contamination averaged 5 × 105 dpm alpha. 

Airborne contamination was monitored by a continuous air sampler. Work was interrupted when the 

airborne activity was measured at the SRS administrative control limit. In another section of the form 

(not shown) it was indicated that external dose was tracked by pocket chamber dosimeters. 

Subcontractor CTWs wore respiratory protection and some of the subcontractor CTWs who were 

involved in this work were monitored by bioassay.

This work was also monitored on an intermittent basis. External dose was tracked by pocket chamber 

dosimeters. Both alpha and beta-gamma transferable contamination were measured at less-thandetection values. While this work had little potential for intake of radionuclides, some of the 

subcontractor CTWs who were involved in this work were monitored by bioassay.

and prepared the hood for burial. The work was monitored at the start and conclusion of work. Both 

alpha and beta-gamma transferable contamination were measured at less-than-detection values. 

Subcontractor CTWs used respiratory protection, and some of the subcontractor CTWs who were 

involved in this work were monitored by bioassay.

contamination was found, HP observed no unusual conditions and did not detect any surface or 

airborne contamination. Continuous air monitoring results available for the work area show no results 

greater than detection levels (DuPont 1983r).

contamination were measured at less-than-detection values. DuPont and subcontractor CTWs used 

respiratory protection. Some of the subcontractor CTWs who were involved in this work were 

monitored by bioassay.

6.0 EVALUATION OF INCIDENT MONITORING 

Area contamination and worker contamination were actively monitored during the performance of 

subcontractor jobs. While ORAU has only partial records, some subcontractor CTW contamination 

incidents were found during review of the RSL and worker bioassay history records. The types of 

work performed and potential for radiation exposures were similar for both DuPont and subcontractor

CTWs. While Job Plans and SWPs indicated the expected conditions, monitoring during the tasks 

might have determined whether workers were exposed and if bioassays were necessary. When air 

sampling and contamination monitoring showed no activity, bioassays might have not been requested 

even in those cases where the plans or permits indicated an uptake was possible. Examples of 

incidents involving subcontractor CTW associated with Job Plan files and RSL reviewed in this report

with follow-up actions include: 

• In February 1980 a subcontractor CTW working on a multiple-week project to dismantle 

equipment in B-147 was found to be working with high airborne alpha radioactivity without a 

respirator by HP, which was monitoring the work intermittently (DuPont 1981a, p. 24). Results 

of fecal, urine, and in vivo bioassay indicated the worker received an intake of less than 10% 

of the maximum permissible body burden (ORAUT 2017; DuPont 1974–1984, pp. 290–295).

• In July 1983, 13 subcontractor CTWs were contaminated while working in C-005 under a Job 

Plan for the basement of Building 773-A (DuPont 1983b, pp. 80-81). A redacted copy of the 

Job Plan is provided in Figure 6-1. HP monitored the work intermittently. HP requested 

bioassay samples to be collected from each worker. The reported results ranged from <0.1 to 

0.5 dpm/L plutonium and from <0.3 to 0.5 dpm/L americium (DuPont 1987d, pp. 36–57). 

Figures 6-2 and 6-3 show redacted copies of two of the special bioassay request cards 

completed by HP in response to the contamination and updated with results of analysis by the

laboratory. These cards demonstrate the range of the reported bioassay results for 

americium.

The hands of one of the subcontractor CTWs working on the painting task were contaminated 

while removing contaminated coveralls. The CTW apparently touched his face resulting in 

nasal contamination. HP surveyed the worker, performed nasal monitoring followed by urine 

bioassay; 0.1 dpm/L Pu was reported for the worker (DuPont 1987d, p 54). Figure 6-4 shows 

a description of contamination with follow-up monitoring.

• On November 11 and 12, 1983, 12 subcontractor CTWs replacing an MCC in B-048 received 

potential intakes of plutonium (DuPont 1983c, pp. 193-196). Urine bioassay samples were 

collected from all 12 workers. The result for one worker was reported as 0.2 dpm/1.5 L of 

plutonium, while results for the rest were reported as <0.1 dpm/1.5 L. All workers were 

reported to have <0.3 dpm/1.5 L americium (ORAUT 2017; DuPont 1986i, p. 106; 1987d, 

pp. 60–68).

• On November 4, 1986, alpha airborne contamination above the normal level was observed in 

B-005 by HP as a subcontractor CTW was decontaminating the room (DuPont 1986c, pp. 11–

17). The worker picked up a bag with removable contamination of 1 × 106 dpm without 

wearing a respirator. HP requested special urine and fecal bioassay samples. Results of 

those analysis revealed intakes of 6,880 dpm insoluble 239Pu, 1,200 dpm soluble 239Pu, 

3,550 dpm insoluble 241Am, and 644 dpm soluble 241Am. The worker was subsequently added 

to the Transuranic Registry (ORAUT 2017; DuPont 1986d).

• On December 5, 1986 the gloves of two subcontractor CTWs were contaminated to 6,000 dpm 

alpha while working in B-005 installing a new high-level drain assembly. Outer overalls of two 

other subcontractor CTW working on the portion of the drain assembly in C-005 were 
Document No. ORAUT-RPRT-0083 Revision No. 00 Effective Date: 06/27/2017 Page 23 of 51

 

contaminated to 20,000 dpm alpha. The inner coveralls of both coveralls were surveyed at 

<100 dpm alpha. Figure 6-5 shows portions of the RSL and Job Plan. 

• These examples demonstrate that HP monitored work performed by subcontractor CTWs well. 

Some tasks were monitored continuously and others intermittently. The examples show that 

HP used workplace and worker observation, radiation surveys, and constant air monitoring to 

monitor work conditions as well as follow-up surveys and bioassay to assess worker 

contamination and possible assimilation of radionuclides. Additional examples on incidents 

involving subcontractor CTW are available.

7.0 CONCLUSIONS

The ORAU Team has determined that subcontractor CTWs were monitored along with DuPont CTWs 

for exposures to occupational radiation exposures during the years 1980 through 1986.

As discussed in Section 3.1 and shown in Table 3-1, 99% of DuPont CTWs and 97% of subcontractor 

CTWs in this evaluation from 1980 through 1986 were monitored for external dose. 100% of 

subcontractor CTWs were monitored for external dose from 1980 to 1982, 1984, and 1986. SRS 

monitored both DuPont and subcontractor CTWs for external dose similarly.

In relation to monitoring for internal intake of radionuclides, bioassay data shows 67.0% of randomly 

selected subcontractor CTW wearing respiratory protection were monitored for intakes of 

radionuclides from 1980 through 1986. Almost 38% of those workers were on routine monitoring for 

one or more radionuclides in accordance with DuPont (1971). In cases for which bioassay data was 

not found for a worker or job, the Team found bioassay results for a coworker on the same job for

another 26% of the randomly selected set of workers wearing respiratory protection. By procedure,

either urine bioassay or in vivo analysis was requested from all SRS workers including subcontractor 

CTWs at termination (DuPont 1991; ORAUT 2017; DuPont 1983–1985). The bioassay results, 

incident reports, radiation survey logsheets, and air monitoring reports evaluated for this report show

that subcontractor CTWs were monitored for intakes of radionuclides routinely, by event-driven 

sampling, and by termination sampling.

The work locations listed in Job Plans for work performed by subcontractor CTWs were surveyed and 

swiped for contamination on routine, defined frequencies and intermittently throughout jobs as 

reported in Attachment B, Table B-2. Similarly, the airborne concentrations of those work locations 

were continuously monitored for alpha and beta-gamma radioactivity. These data show jobs 

performed by subcontractor CTWs were monitored in the same manner and with the same 

procedures as work performed by DuPont CTWs. HP provided protective clothing and respiratory 

requirements and guidance for all Job Plans before work commenced. HP monitored the work and 

conditions under all the Job Plans reviewed by the Team for this evaluation. All jobs were monitored 

at work start-up and were then monitored continuously or intermittently afterwards depending on the 

work and conditions of the location.

The Team has included examples of subcontractor CTWs involved in contamination incidents, one of 

which led to a subcontractor CTW being added to the Transuranic Registry. The Team has shown 

subcontractor CTWs and their clothing, when contaminated or involved in a contamination incident, 

were surveyed and monitored by HP. More records of such incidents are available. Most of the Job 

Plan and permit files evaluated for this report did not result in contamination or event-driven bioassay.

The Team finds subcontractor CTWs were monitored for both external and internal radiation exposure 

by external dosimetry, bioassay, continuous air monitoring, contamination monitoring, and radiation 

surveys. Work by subcontractor CTWs was preplanned. Instructions for work and protective 

measures and clothing were specified in the same manner and on the same forms as work to be by 

DuPont CTWs. Like DuPont CTWs, subcontractor CTWs were monitored in accordance with HP 

procedures (DuPont 1991). Many subcontractor CTWs, such as the 39% of 88 workers in Table 4-1, 

were routinely monitored by bioassay. Subcontractor CTWs were also monitored as incidents 

occurred. While some subcontractor CTWs might not have been monitored by bioassay, the report 

has shown their coworkers were monitored. As a result, radiation dose to subcontractor CTWs may 

be reconstructed using external and routine or event-driven bioassay monitoring data available for the 

worker, using coworker data, or using a combination of the two.

TYPES OF FORMS (continued)

Four types of forms provided in the Job Plan were reviewed to identify workers. Figure A-1 shows the 

Job Plan form in the 1980s. Workers from all SRS Rolls, including those subcontractor CTWs who 

were approved to work on specific jobs, were recorded on this form. The job description, job 

evaluation, and protective clothing requirements were listed. Note that the protective clothing list also 

included a respirator. SRS added a supplemental page to the Job Plan form in the mid-1980s.

TYPES OF FORMS (continued)

The SWP form (Figure A-2) was used to record subcontractor CTW assignment and monitoring as 

they worked on a specific job. Job description, instructions, and protection clothing requirements 

were listed on the permit. Note that certain clothing requirements are in the Instructions section and

TYPES OF FORMS (continued)

A Work Clearance Permit (Figure A-4) was used with some Job Plans. The permit provided detail on 

the safety requirements of the specific job and a written authorization to begin work. This form was 

often used along with the Job Plan form, but at times SRS appears to have used this form as the only 

controlling form for a task. These forms were also used for non-radiological work.

TYPES OF FORMS (continued)

The Confined Space and Vessel Entry Log was used with tasks that required confined space entry. 

The first page provided reason, work description and instructions, entry preparation, protective 

equipment, preventive measures, and approvals for entry of confined space. The second page

(Figure A-5), was used to log entry of workers.

JOB DESCRIPTIONS (continued)

Tables B-1 and B-2 document the findings from review of the Job Plans, workplace monitoring, and 

worker bioassay data associated with the 133 distinct subcontractor CTW-job pairings and their 

bioassay data. 

Table B-1 provides descriptive data for each Job Plan. The table lists the date of the Job Plan, the 

craft of subcontractor CTW, and a description of the task to be done. Job Plans were numbered in 

date order. Table B-2 provides, in the same date order, workplace conditions, respiratory 

requirements, and accounting of bioassay results for subcontractor CTW matched to the Job Plan. A 

subcontractor CTW was marked as being sampled for a particular radionuclide if the sampling time 

difference was less than or equal to the frequency for the radionuclide for Building 773-A in DuPont 

(1971). SRS HP procedures were used uniformly across SRS during the time of this evaluation. 

Therefore, workers on routine bioassay were sampled in the area assigned at the time the bioassay 

was requested. Additionally, subcontractor CTWs might have been sampled in relation to work in 

other areas. Certain workers might have worked in other areas at SRS during the same year they 

worked under a Job Plan or permit at Building 773-A. Some bioassays might have been a result of 

that work and unrelated to the plans and permits for Building 773-A, but results of that bioassay 

sampling might still bound intakes from work in Building 773-A.
